Which type of magnesium is best for sleep?

When it comes to improving sleep quality, Andrew Huberman recommends Magnesium Threonate and Magnesium Bisglycinate due to their high bioavailability and ability to promote deep sleep. Magnesium Threonate is highly effective as it crosses the blood-brain barrier and engages the GABA pathway, which helps turn off certain areas of the brain for better sleep onset and depth 1. Meanwhile, Magnesium Glycinate is also a good choice, as it helps with overall relaxation, benefiting hormone balance and stress regulation, which can improve sleep quality 2.
